I have one file with a lot of numeric data... and I need to sum
all that data...
That is my actual code:
module main;
import std.stdio;
import std.file;
import std.conv : to;
int main(string[] args)
{
auto f = File(oi.txt);
auto r = f.byLine();
auto tot = 0;
O, real intresting the mode functional style!!!
Like linq!
hahah
Btw, it's work very well, thansk!!!
But, how I can insert an ',' comma to separe the decimal place ?
( the last 2 digits )
I can't find a insert instruction in std.string or std.array

I have a string X and I need to insert a char in that string...
auto X = 100;
And I need to inser a ',' in position 3 of this string..., I try
to use the array.insertInPlace, but, not work...
I try this:
auto X = 100;
auto N = X.insertInPlace(1,'0');
Sorry..
I mean:
auto X = 100;
auto N = X.insertInPlace(3,',');

I used that solution:
string InsertComma(string val)
{
return val[0 .. $-2] ~ , ~ val[$-2 .. $];
}

Hi :)
I need to sum a list of numbers... but, when I calculate the sum
of this numbers, I got a simplify representation of sum:
2.97506e+,12
How I can make to get the correctly representation of this number
?
basically format
I read a cobol struct file...
From pos X to Y I have a money value... but, this value don't
have any format..
0041415
The 15 is the cents... bascally I need to put the ( comma ), we
use comma to separate the cents, here in Brazil...

I have this code in C++
//...
char image[0x800];
//...
auto dosh = reinterpret_castIMAGE_DOS_HEADER*(image[0]);
dosh-e_magic = *(WORD*)MZ;
dosh-e_cblp = 0x90;
dosh-e_cp = 3;
dosh-e_cparhdr = 4;
dosh-e_maxalloc = 0x;
dosh-e_sp = 0xb8;
dosh-e_lfarlc = 0x40;
Ok, thanks thanks!!!
Have a lot of thinks I need to learn
When I generate the exe file, something is wrong with this:
dosh.e_magic = cast(WORD)*MZ.ptr;
When the PE file is generate in EXE have just the M of MZ...
Oh, thanks a lot!!
With a little change all work!
look:
struct IMAGE_DOS_HEADER {
WORD e_magic,
e_cblp,
//...
void main() {
import std.stdio;
import std.file;
import core.stdc.string;
auto dosh = cast(PIMAGE_DOS_HEADER)image.ptr;
Look at line 114 of my code: http://dpaste.com/3B5WYGV
Have a more better way to make this conversion ?
*(DWORD*)PE\0\0 ?
And some other strange thing is, the generate struct in PE file
is wrong.. look at imagens...
As it should be...: http://i.imgur.com/4z1T3jF.png
And how is being generated...: http://i.imgur.com/Oysokuh.png

I don't see much need for such aliases.
Ok, how I can reduce the number of aliaSs ?
I suggest to avoid magic constants like that 0x80, like I have
avoided it here:
memcpy(image[IMAGE_DOS_HEADER.sizeof],
Btw, I need to start that part of code in x80
Look, that is my C++ code base:
immutable ubyte[5] stub = xb8 01 4c cd 21.representation;
that is a Real-Mode Stub Program

Soory, I not understand, why lose the optlink ?
Read the libs is simple, but, the linker do the brute force!

Hi :)
I made this function to inverse the bytes in intger or T
(possible) type...
int reverseBytes(T)(T val)
{
int retVal = 0;
static if(is(T == string))
retVal = to!int(val);
return (retVal 0x00FF) 24 |
(retVal 0xFF00) 8
Thanks, but, when I convert I recive a 'c' in the front of my
number...
uint reverseBytes(uint val)
{
import core.bitop : bitswap;
return bitswap(val);
}
//...
writefln(%x, reverseBytes(0x00402030));
//...
// output: c040200
On Tuesday, 15 July 2014 at 12:16:26 UTC,
Something is wrong between our communication...
I am wanting to do something better to order the bytes, for this
my code...
https://gist.github.com/bencz/3576dfc8a217a34c05a9
For example, in that case:
injectData(image[0x207], x30204000);
It's more simple to use something like:
Strange..., why '@' ?

Oh!
I used the RefCounted because this:
The proposed C++ shared_ptr, which implements ref counting,
suffers from all these faults. I haven't seen a heads up
benchmark of shared_ptr vs mark/sweep, but I wouldn't be
surprised if shared_ptr turned out to be a significant loser in
terms of both
I have this struct:
enum AddrType { Abs, RVA, Rel };
struct Address
{
shared_ptrDWORD addr;
AddrType type;
Address(): type(Abs) {}
Address(DWORD addr, AddrType type):
addr(shared_ptrDWORD(new DWORD(addr))), type(type) {}
Address(shared_ptrDWORD addr, AddrType type):
Yes yes, I will use the ref... is more safer!
I will try to re-create my logic...
btw, how is the best way to reinterpret this ??:
mapstring, Address syms;
and:
vectorpairDWORD, Address values;
vectorpairDWORD, shared_ptrDWORD addrs;

Hi everyone,
I would like an honest opinion.
I have a beginner level (able to do very small programs) in a few
languages such as python, go, C, guile(scheme) and common lisp.
I want to pick a language and go deep with it and focus on only
one for at least the next 2 years or so.
Should I
